Neil wrote in from the UK, asking about Panasonic’s EY7552 18V twin hammer impact wrench. I sent him a reply, but the email bounced back with an error message that his mailbox is unavailable.
I’m considering buying a Panasonic impact wrench for scaffolding work.
Would this be suitable and what is the cost of the latest twin hammer version?
I wish I could answer this, but I have not tested the new Panasonic impact wrench firsthand, and I don’t know of anyone that has even seen one in person.
It *should* be suitable for scaffolding work, as it is said to have a pin through-hole socket retention mechanism. The impact should have more than enough torque, and so my main concern would be socket retention, as you don’t want sockets slipping off the anvil and falling onto other workers or passerby’s below.
The typical UK dealers I look at don’t carry this particular product, but one dealer I found online has the kit for £465.60 including VAT.
The new Panasonic EY7552 twin hammer impact wrench is currently available in the USA as well:

If you don’t absolutely need the Panasonic impact’s IP56 dust and water resistance, Milwaukee’s M18 FUEL brushless heavy duty impact is a very good alternative.
I still have questions of my own about the twin hammer aspect of the new impact wrench, regarding how it achieves increased torque, reduced vibration, and lower noise. It seems counter intuitive that a double hammer design would be less noisier. I would think that two impacts at the same time would create more noise. I asked Panasonic about this months ago, but they never got back to me.
If anyone has experience with this particular model, please chime in with your impression of it!
